Description

Technical Field

[0001] The invention relates to the technical field of fertilization tanks, and in particular to a brackish water drip irrigation anti-clogging fertilization tank. Background Art

[0002] The shortage of freshwater resources has become a key bottleneck restricting the sustainable development of my country's agriculture and threatening food security. The rational use of brackish water drip irrigation has become one of the effective measures to alleviate the contradiction between freshwater supply and demand. At present, the brackish water drip irrigation technology has changed from the traditional single irrigation function to the multi-function direction of irrigation, fertilization, etc. The fertilizer tank is an indispensable and important equipment in the brackish water drip irrigation system. However, brackish water contains a large number of inorganic salt ions and microorganisms, which will inevitably form chemical-biological composite dirt in the fertilizer tank and precipitate in the fertilizer tank, causing blockage at the outlet of the fertilizer tank. In addition, the addition of fertilizers will react with calcium and magnesium ions in the brackish water source to form insoluble precipitation, which aggravates the blockage of the fertilizer tank. In addition, the chemical reaction of fertilizers in the fertilizer tank leads to premature loss of fertilizers, which reduces the efficiency of fertilizer use. Therefore, there is an urgent need for an anti-clogging fertilizer tank suitable for brackish water drip irrigation systems.

[0003] At present, most of the anti-clogging fertilizer tank products at home and abroad use a high-mesh filter to filter out impurities in the water source or use a stirring device to fully stir the fertilizer to prevent the fertilizer from settling during the fertilization process and clogging the discharge pipe. However, since there are a large number of salt ions and microorganisms in brackish water, the filter can only intercept the sediment in the water, but cannot effectively intercept the salt ions and microorganisms in the water, and cannot prevent the salt ions and fertilizers from chemically reacting in the tank to form precipitation. At the same time, the stirring device in the fertilizer tank cannot effectively remove the precipitation at the bottom of the fertilizer tank. Summary of the invention

[0004] (I) The problem to be solved by the present invention is that since brackish water contains a large amount of salt ions and microorganisms, the filter can only intercept the mud and sand in the water, but cannot effectively intercept the salt ions and microorganisms in the water, and cannot prevent the salt ions and fertilizers from chemically reacting in the tank to form precipitation. At the same time, the stirring device in the fertilization tank cannot effectively remove the precipitation at the bottom of the fertilization tank.

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 6 As shown, one embodiment of the present invention provides a brackish water drip irrigation anti-clogging fertilization tank, comprising a tank body 1, a frequency conversion magnetization device 17, an ultraviolet lamp 22, a water inlet pipe 6, a stirring mechanism, a dirt flushing pipeline mechanism and a control box; a discharge pipe 102 is provided at the bottom of the tank body 1, a valve body 18 for controlling the on-off of the discharge pipe 102 is provided on the discharge pipe 102, a feed port 101 is provided at the top of the tank body 1, and a stirring mechanism is provided on the tank body 1 for stirring the brackish water and fertilizer inside the tank body 1;

[0037] The variable frequency magnetization device 17 is used to reduce the solubility of the salt ions in the slightly salty water in the water inlet pipe 6, and to slow down the chemical reaction between the salt ions in the water body inside the tank body and the chemical reaction with the fertilizer;

[0038] At least one ultraviolet lamp 22 is installed on the inner top wall of the tank body 1. The ultraviolet lamp 22 is used to inhibit the growth of microorganisms in the water body in the tank body 1. The ultraviolet lamp 22 is connected to the control box signal;

[0039] The bottom end of the dirt flushing pipeline mechanism extends into the interior of the tank body 1 and is close to the inner bottom wall thereof, and one end of the water inlet pipe 6 is connected to the dirt flushing pipeline mechanism;

[0040] The dirt flushing pipeline mechanism has a first state and a second state. When the dirt flushing pipeline mechanism is in the first state, the water flowing out of the dirt flushing pipeline mechanism flows along the first direction; when the dirt flushing pipeline mechanism is in the second state, the water flowing out of the dirt flushing pipeline mechanism flows along the second direction. The first direction and the second direction are two opposite directions. The control box is used to control the dirt flushing pipeline mechanism to switch between the first state and the second state.

[0041] In this embodiment, brackish water enters the dirt flushing pipeline mechanism from the water inlet pipe 6, and the brackish water is injected into the tank body 1 through the dirt flushing pipeline mechanism. Since the frequency conversion magnetization device 17 can reduce the solubility of the salt ions in the brackish water flowing into the water inlet pipe 6, the chemical reaction between the salt ions in the water body inside the tank body 1 and the chemical reaction with the fertilizer can be slowed down to the greatest extent, thereby effectively reducing the amount of precipitation formed inside the tank body 1. The ultraviolet light emitted by the ultraviolet lamp 22 can inhibit the growth of microorganisms in the water body, effectively control the formation of biological fouling in the tank body 1, and can be used together with the frequency conversion magnetization device 17 to greatly reduce chemical precipitation and biological fouling. The stirring device is turned on to stir the brackish water and fertilizer inside the tank body 1, and the control box controls the dirt flushing pipeline mechanism to switch to the first state. In the first state, the water flowing out of the dirt flushing pipeline mechanism flows along the first direction, which is the same as the stirring direction of the stirring device. The dirt flushing pipeline mechanism is used together with the stirring device to improve the stirring effect and accelerate the dissolution rate of the fertilizer. Then the control box controls the dirt flushing pipeline mechanism to switch to the second state. In the second state, the water flowing out of the dirt flushing pipeline mechanism flows in a second direction, which is opposite to the stirring direction of the stirring device, thereby generating a large amount of turbulence, thereby improving the flushing effect on the sediment on the inner wall of the tank body 1. Since the magnetized brackish water can make the sediment formed on the inner wall of the tank body 1 looser, the stirring mechanism cooperates with the dirt flushing pipeline mechanism to flush and easily flush away the loose sediment, thereby effectively removing the sediment at the bottom of the fertilization tank.

[0042] It can be seen that in this embodiment, the frequency conversion magnetization device 17 is used to reduce the solubility of salt ions in brackish water, so that the chemical reaction between salt ions in the water inside the tank body 1 and the chemical reaction with fertilizer can be slowed down to the greatest extent, thereby effectively reducing the amount of precipitation formed inside the tank body 1. The ultraviolet light emitted by the ultraviolet lamp 22 is used to inhibit the growth of microorganisms in the water body, effectively control the formation of biological fouling in the tank body 1, and use it together with the frequency conversion magnetization device 17 to greatly reduce chemical precipitation and biological fouling. Moreover, since the magnetized brackish water can make the precipitation formed on the inner wall of the tank body 1 looser, the loose precipitation can be easily washed away by the mud and dirt flushing pipeline mechanism and the stirring mechanism, thereby effectively removing the precipitation at the bottom of the fertilization tank. Moreover, the mud and dirt flushing pipeline mechanism can not only improve the stirring effect, accelerate the dissolution rate of the fertilizer, but also improve the flushing effect of the precipitation on the inner wall of the tank body 1.

[0043] As a preferred embodiment, Figure 1 and Figure 5As shown, the dirt flushing pipeline mechanism includes a main pipe 5, a first water outlet pipe 3, a second water outlet pipe 4, a first branch pipe 7, a second branch pipe 8, a first water outlet elbow pipe 9, a second water outlet elbow pipe 10, a third water outlet elbow pipe 11, a fourth water outlet elbow pipe 12, a first electric valve 13, a second electric valve 14, a third electric valve 15 and a fourth electric valve 16. The main pipe 5 is a U-shaped pipe, a circular hole is opened on the middle side wall of the main pipe 5, one end of the water inlet pipe 6 is connected to the circular hole on the side wall of the main pipe 5, the main pipe 5 is located above the tank body 1, and its left and right ends face the tank body 1, the first water outlet pipe 3 and the second water outlet pipe 4 are vertically arranged inside the tank body 1, and are symmetrically arranged about the axis of the tank body 1, and the top ends of the first water outlet pipe 3 and the second water outlet pipe 4 are respectively connected to the two ends of the main pipe 5. Furthermore, a first connecting hole is opened on the side wall of the first water outlet pipe 3 near one end of the main pipe 5, and a second connecting hole is opened on the side wall of the second water outlet pipe 4 near one end of the main pipe 5. The top end of the first branch pipe 7 is connected to the first connecting hole, and the top end of the second branch pipe 8 is connected to the second connecting hole. The bottom ends of the first water outlet pipe 3, the second water outlet pipe 4, the first branch pipe 7 and the second branch pipe 8 are all close to the inner bottom wall of the tank body 1, and the bottom ends of the first water outlet pipe 3, the second water outlet pipe 4, the first branch pipe 7 and the second branch pipe 8 are at the same height.

[0044] Further, such as Figure 5 As shown, the first water outlet bend 9 is connected with the bottom opening of the first water outlet pipe 3, and the water flowing out of the first water outlet bend 9 flows counterclockwise around the axis of the tank body 1, the second water outlet bend 10 is connected with the bottom opening of the second water outlet pipe 4, and the water flowing out of the second water outlet bend 10 flows clockwise around the axis of the tank body 1, the third water outlet bend 11 is connected with the bottom opening of the first branch pipe 7, and the water flowing out of the third water outlet bend 11 flows clockwise around the axis of the tank body 1, and the fourth water outlet bend 12 is connected with the bottom opening of the second branch pipe 8, and the water flowing out of the fourth water outlet bend 12 flows counterclockwise around the axis of the tank body 1.

[0045] Further, the first electric valve 13 is installed on the first water outlet pipe 3 to control the on-off of the first water outlet pipe 3, the second electric valve 14 is installed on the second water outlet pipe 4 to control the on-off of the second water outlet pipe 4, the third electric valve 15 is installed on the first branch pipe 7 to control the on-off of the first branch pipe 7, and the fourth electric valve 16 is installed on the second branch pipe 8 to control the on-off of the second branch pipe 8. The first electric valve 13, the second electric valve 14, the third electric valve 15 and the fourth electric valve 16 are all connected to the control box signal.

[0046] In this embodiment, the second electric valve 14 and the third electric valve 15 are first opened through the control box, and the first electric valve 13 and the fourth electric valve 16 are closed, and the brackish water flows from the water inlet pipe 6 into the main pipe 5, and then flows from the two ends of the main pipe 5 into the second water outlet pipe 4 and the first branch pipe 7 respectively, and finally flows out from the second water outlet elbow pipe 10 and the third water outlet elbow pipe 11. At this time, the water flowing out of the second water outlet elbow pipe 10 flows clockwise around the axis of the tank body 1, and the water flowing out of the third water outlet elbow pipe 11 flows clockwise around the axis of the tank body 1, and the stirring device stirs clockwise around the axis of the tank body 1. The stirring effect can be improved and the dissolution rate of the fertilizer can be accelerated. Finally, the second electric valve 14 and the third electric valve 15 are closed through the control box, and the first electric valve 13 and the fourth electric valve 16 are opened, and the brackish water flows from the water inlet pipe 6 into the main pipe 5, and then flows into the first water outlet pipe 3 and the second branch pipe 8 from both ends of the main pipe 5 respectively, and finally flows out from the first water outlet elbow 9 and the fourth water outlet elbow 12. The water flowing out of the first water outlet elbow 9 flows counterclockwise around the axis of the tank body 1, and the water flowing out of the fourth water outlet elbow 12 flows counterclockwise around the axis of the tank body 1. Since it is opposite to the stirring direction of the stirring device, a large amount of turbulence can be formed inside the tank body 1, thereby improving the flushing effect and accelerating the shedding of the sediment on the bottom wall of the tank body 1.

[0047] It should be noted that the frequency conversion magnetization treatment of brackish water can reduce the solubility of salt ions in the water body, slow down the chemical reaction between salt ions in the water body and the chemical reaction with fertilizers to the greatest extent, and effectively reduce the formation of precipitation. In addition, the magnetization treatment of brackish water can make the formed precipitation looser, and combined with the mud and dirt flushing pipeline mechanism, the mud and dirt flushing pipeline mechanism greatly improves the flushing effect, so that the precipitation at the bottom wall of the tank body 1 is easily flushed away by the water flow, and the precipitation at the bottom of the tank body 1 can be effectively removed.

[0048] As a preferred embodiment, Figure 4 As shown, an ultraviolet lamp 22 is installed on the inner top wall of the tank body 1. The ultraviolet light emitted by the ultraviolet lamp 22 can inhibit the growth of microorganisms in the water body, effectively control the formation of biological fouling in the tank body 1, and can be used together with the variable frequency magnetization device 17 to greatly reduce chemical precipitation and biological fouling. The ultraviolet lamp 22 is connected to the control box signal, and the control box can control the light intensity of the ultraviolet lamp 22.

[0049] In this embodiment, the ultraviolet intensity of the ultraviolet lamp (22) is 70 μW / cm 2 -180μW / cm 2 .

[0050] In order to increase the flow rate of the water in the tank body 1 during stirring and flushing, as Figure 4As shown, the bottom of the tank body 1 is set to a cone shape, so that when stirring, the stirring mechanism can more easily speed up the flow rate of water at the bottom of the tank body 1, thereby improving the flushing effect on the sediment and the dissolution rate of the fertilizer.

[0051] As an optional embodiment, the stirring mechanism is provided in various forms, and the specific form is not specifically limited, as long as it can achieve a stirring effect. In this embodiment, the most traditional stirring structure is adopted, that is, it includes a motor 21, a stirring shaft 19 and a paddle 20, the stirring shaft 19 is rotatably installed in the tank body 1, the bottom end of the stirring shaft 19 is close to the inner bottom wall of the tank body 1, the motor 21 is installed on the top of the tank body 1, and the output end of the motor 21 is connected to the top of the stirring shaft 19, and the paddle 20 is installed at the bottom end of the stirring shaft 19.

[0052] It should be noted that if Figure 2 As shown, a water outlet is provided on the bottom side wall of the tank body 1, a discharge pipe 102 is sealedly installed at the water outlet, a valve body 18 is installed on the discharge pipe 102, and the valve body 18 is an electric valve connected to the control box signal.

[0053] In this embodiment, if Figure 1 As shown, the variable frequency magnetization device 17 is installed on the top surface of the tank body 1, and the variable frequency magnetization device 17 includes a frequency converter, a coil and a digital display, wherein the coil is wound on the water inlet pipe 6. The principle of the variable frequency magnetization device 17 is to use the frequency converter to adjust the parameters of the alternating current so that the alternating magnetic field in the coil changes, thereby changing the physical or chemical properties of the magnetized substance. Specifically, by connecting the input alternating current to the coil through the frequency converter, the brackish water to be magnetized flows through the coil. The function of the frequency converter is to change the alternating magnetic field in the coil by adjusting the parameters of the alternating current as needed. This change, under the action of the magnetic field, can change the physical and chemical properties of the magnetized brackish water, so as to reduce the solubility of salt ions in the brackish water flowing into the water inlet pipe 6, and can slow down the chemical reaction between the salt ions in the water body and the chemical reaction with the fertilizer to the greatest extent, thereby effectively reducing the amount of precipitation formed inside the tank body 1.

[0054] In this embodiment, the sweep frequency range of the variable frequency magnetization device 17 is 0-50KHz, and the sweep period is: 1.5s~1.9s; the sweep frequency can be adjusted by the control module, and the material of the pipeline coil is copper wire, and the cross-sectional area is: 0.6~1.2mm 2 .

[0055] Optional, such as Figure 1 and Figure 2 As shown, the tank body 1 is installed on a support frame 2 , and the support frame 2 serves to support the tank body 1 .

[0056] In this embodiment, if Figure 6As shown, the motor 21, the variable frequency magnetization device 17, the ultraviolet lamp 22, the first electric valve 13, the second electric valve 14, the third electric valve 15 and the fourth electric valve 16 are respectively connected to the control module signal of the control box. Among them, the ultraviolet lamp 22 is externally connected to a power supply. Specifically, the control box controls the speed of the motor 21 through a pulse width modulation (PWM) signal. The control box first receives instructions or set values ​​from the user. These instructions can be speed targets or steering commands. Then the control box converts these instructions into parameters required by the control algorithm, including calculating the target torque and speed of the motor 21. Then the control box generates a PWM signal, which is a digital signal. The voltage and current of the motor 21 are controlled by adjusting the duty cycle of the signal (that is, the proportion of the high level time to the total time). The larger the duty cycle, the higher the voltage and current of the motor 21, thereby increasing the speed; otherwise, the speed is reduced.

[0057] The control box can control the light intensity by adjusting the power supply of the ultraviolet lamp 22 light source. Specifically, increasing or decreasing the power input current can change the output intensity of the light source.

[0058] In addition, the magnetic field size of the variable frequency magnetization device 17 is mainly adjusted by adjusting the parameters of the frequency converter, and the change of the magnetic field depends on the adjustment of the parameters of the alternating current. Specifically, by adjusting the parameters of the alternating current through the frequency converter, the alternating magnetic field in the coil can be changed, thereby affecting the physical or chemical properties of the magnetized material.

[0059] The brackish water drip irrigation anti-clogging fertilization tank in this embodiment further includes a flow meter installed on the discharge pipe 102 , and the flow meter is used to detect the flow of the discharge pipe 102 . When the detected real-time flow rate is less than the set value, it indicates that the blockage of the discharge pipe 102 is serious. At this time, the control module increases the magnetic field of the variable frequency magnetization device 17 by adjusting the parameters of the frequency converter, and increases the light intensity of the ultraviolet lamp 22 by adjusting the power supply of the ultraviolet lamp 22. The control module increases the speed of the motor 21 by increasing the duty cycle. In this way, the variable frequency magnetization device 17 greatly reduces the solubility of the salt ions in the brackish water flowing into the water inlet pipe 6, and slows down the chemical reaction between the salt ions in the water body inside the tank body 1 and the chemical reaction with the fertilizer to the greatest extent, thereby effectively reducing the amount of precipitation formed inside the tank body 1 to reduce the probability of blockage of the discharge pipe 102. At the same time, the light intensity of the ultraviolet light emitted by the ultraviolet lamp 22 is increased, which can effectively inhibit the growth of microorganisms in the water body, effectively control the formation of biological fouling in the tank body 1, and also reduce the probability of blockage of the discharge pipe 102. Finally, the speed of the motor 21 is increased to cooperate with the mud and dirt flushing pipeline mechanism to quickly discharge a small amount of precipitation formed inside the tank body 1 from the discharge pipe 102. In this way, when the blockage of the discharge pipe 102 is serious, the control module adjusts the parameters of the variable frequency magnetization device 17, the ultraviolet lamp 22 and the motor 21 so that the device can operate at the optimal parameters to achieve low energy consumption and high efficiency anti-blockage effects.
